Abstract
A degradable plant composition used for making environment protection type flowerpot and artworks is prepared from plant fibre powder and urea-formaldehyde resin powder through proportional mixing, adding water, stirring and die pressing. Its advantages are full degradation, high air permeability, and low cost.
Description
Technical field:
The present invention relates to a kind of degradable plant composite material and manufacturing process thereof that is suitable for making environmental protection type flowerpot and environment-protective handicraft.
Background technology:
What use in a large number on the market at present is pottery and plastic flowerpot, though jardiniere is attractive in appearance, and the cost height, frangible, can not degrade; Plastic flowerpot not only can not be degraded, and is acknowledged as " white pollution ", and destroys the water-permeable of soil, very easily causes seedling death when changing basin.The material for making lunch box for environment protection that the flowerpot of studying has makes into; but it needs more than several 130 orders of rice husk order; and externally need coating; and because the requirement of cutlery box is that requirement is degraded fast; therefore this flowerpot cost height not only; the manufacturing process complexity, and it is attractive in appearance, durable to adapt to the environmental protection type flowerpot need, the requirement that can degrade when abandoning.Flowerpot as for the other materials manufacturing all exists different defectives, and is just mouldy more than 10 days as the flowerpot that paper pulp is made, and broken, paper will be cut for forest, and contaminated wastewater is arranged in the manufacturing processed, is not good environment-friendly materials; With the flowerpot that urea-formaldehyde resin adhesive is made, shortcoming is a long processing time, same material and thickness, want ability moulding more than 3 minutes, the preservation period of Resin adhesive is not long, approximately has only a week, also need add solidifying agent, the main material ore powder also is a non-degradable, is a kind of flowerpot of matrix material.
Summary of the invention:
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of degradable plant composite material and manufacturing process thereof are provided, this material not only can be degraded fully, and good permeability, is difficult for going mouldy, and long preservative period is made easyly, and cost is low.
The present invention is for achieving the above object by the following technical solutions:
A kind of degradable plant composite material is formulated by plant fiber powder, Precondensed UreaFormaldehyde Resin rubber powder, and its proportioning is that (by weight) is as follows:
Plant fiber powder 45-80%
Precondensed UreaFormaldehyde Resin rubber powder 20-55%
Plant fiber powder can be rice hull cellulose powder, bamboo fibers powder, wood fiber powder, the dried fiber powder of straw, coir powder, Pericarppium arachidis hypogaeae fiber powder or reed fiber powder in the such scheme; Also can add in the prescription plant fiber powder and Precondensed UreaFormaldehyde Resin rubber powder gross weight 3% with interior Zinic stearas.
Manufacturing process of the present invention is: be crushed to 10-150 purpose plant fiber powder and add that the Precondensed UreaFormaldehyde Resin rubber powder evenly stirs, and adding aqueous vapor, churning time is 5-30 minute, injecting mould then pressurizes, die temperature is the 100-180 degree, mould remaining time will be put 1-3 time gas at 1-5 minute in the pressure process, pressure is 7-15kg/cm
2
The flowerpot of made of the present invention is to adopt the Precondensed UreaFormaldehyde Resin rubber powder to be made in conjunction with 60 order rice husks, and the Precondensed UreaFormaldehyde Resin rubber powder is as stick, and formaldehyde has the function of mildew-resistant.Because good fluidity, so rice husk do not need too carefully, makes flowerpot seem the comparison solid, and is attractive in appearance, pulverizes rice husk and can economize a lot yet.The rubber powder preservation period can reach more than half a year, even take good care of and to reach more than 1 year, the flowerpot that plant fiber powder is done can be not mouldy under natural situation, but lose bury in, can absolutely degrade, do not produce the three wastes in process of production, molding time also needed only one minute, did not also need solidifying agent, and be to use agricultural wastes, and at last can also back to nature.Zinic stearas can help that material flows, the demoulding, increase water-repellancy.
Description of drawings:
Fig. 1 is a manufacturing process flow diagram of the present invention.
Embodiment:
The embodiment of the invention 1:
Formulated by plant fiber powder, Precondensed UreaFormaldehyde Resin rubber powder, its proportioning is that (by weight) is as follows:
Plant fiber powder 45-80%
Precondensed UreaFormaldehyde Resin rubber powder 20-55%
The manufacturing process of degradable plant composite material of the present invention is crushed to the 10-150 purpose and plants
The fibres powder adds that the Precondensed UreaFormaldehyde Resin rubber powder evenly stirs, and adds aqueous vapor, and churning time is 5-30 minute, inject mould then and pressurize, die temperature is the 100-180 degree, and mould remaining time was at 1-5 minute, will put 1-3 time gas in the pressure process, pressure is 7-15kg/cm
2
Embodiments of the invention 2:
Plant fiber powder can be rice hull cellulose powder, bamboo fibers powder, wood fiber powder, the dried fiber powder of straw, coir powder, Pericarppium arachidis hypogaeae fiber powder or reed fiber powder; Can add in the prescription plant fiber powder and Precondensed UreaFormaldehyde Resin rubber powder gross weight 3% with interior Zinic stearas, best proportioning is:
Plant fiber powder 70%
Precondensed UreaFormaldehyde Resin rubber powder 30%
2% of Zinic stearas plant fiber powder and Precondensed UreaFormaldehyde Resin rubber powder gross weight
Plant fiber powder adds that Precondensed UreaFormaldehyde Resin rubber powder and Zinic stearas evenly stir after being crushed to 60 orders, and adds the aqueous vapor of material gross weight 16%, and churning time is 10 minutes, injects mould then and pressurizes, and pressure is 10kg/cm
2, die temperature is 130 degree, mould remaining time will be put gas 2 times at 1 minute in the pressure process, when pressing mold began for 10 seconds, put 1 second gas, every 30 seconds of venting for the first time the time, put the gas in 1 second again; After the depanning, irregular corner is repaiied, dry after also can spraying waterproof paint, gain in strength.
